Optical disk device with release

1. An optical device, comprising: a main support unit to lift and/or lower to respectively couple and/or uncouple an optical medium on/from a turn-table; a slider to lift/lower the main unit; and a releasing unit to disengage portions of the slider from a driving source which drives the slider to manually move the slider upon insertion of a pin into the optical device.

2. The optical device of claim 1 , wherein the main support unit comprises an optical pickup unit for recording/reproducing data on/from the optical medium.

3. The optical device of claim 1 , wherein the slider comprises a rack connected by a gear to a driving source to linearly move the main unit.

4. The optical device of claim 3 , wherein the releasing unit disengages the gear from the rack for permitting the manual movement of the slider upon the insertion of the pin into the optical device.

5. The optical device of claim 4 , wherein the releasing unit comprises a releasing lever comprising an inclined surface and a gear moving unit, the inclined surface and the gear moving unit being positioned in respective opposite directions with respect to a hinge, wherein when the pin is inserted in the optical device and presses against the inclined surface, the releasing lever is rotated around the hinge, such that the gear moving unit disengages the gear from the rack.

6. The optical device of claim 5 , wherein the releasing unit further comprises an elastic member applying an elastic force to the gear, such that when the pin is removed from the optical device, the releasing lever and the gear are elastically forced to return to an original position by the elastic force of the elastic member.

7. The optical device of claim 6 , wherein an edge of the gear is chamfered.

8. The optical device of claim 1 , further comprising: a slot; and a lever unit to guide the optical medium through the slot to insert the optical medium into the optical device such that the optical medium is concentric with the turn-table and to unload the optical medium in a direction opposite to the loading direction, wherein, when the pin is inserted into the optical device, the rack is correspondingly forced to disengage from the gear, such that the slider is thereby caused to move by the insertion movement of the pin, and the optical medium is correspondingly caused to uncouple from the turn-table and unload from the optical device through the slot.

9. The optical device of claim 1 , wherein the optical medium is a disk.

10. An optical medium releasing method, comprising: lifting and/or lowering to respectively couple and/or uncouple an optical medium on/from a turn-table upon respective loading or unloading of the optical medium from a optical device; and selectively engaging portions of a slider of the optical device to manually move the slider upon insertion and removal of a pin into and out of the optical device.

11. The optical medium releasing method of claim 10 , further comprising recording and/or reproducing data from the optical medium while coupled within the optical device.

12. An optical medium releasing method, comprising: lifting and/or lowering to respectively couple and/or uncouple an optical medium on/from a turn-table upon respective loading or unloading of the optical medium from a optical device; inserting a pin into the optical device; and disengaging portions of a slider of the optical device to manually move the slider upon the insertion of the pin into the optical device.

13. An optical medium releasing method, comprising: positioning a main support unit for lifting and/or lowering to respectively couple and/or uncouple an optical medium on/from a turn-table; positioning a slider for lifting/lowering the main unit; and positioning a releasing unit for disengaging portions of the slider from a driving source which drives the slider to manually move the slider upon insertion of a pin into the optical device.

14. A slot-in type optical device framing, comprising: a slot entrance for insertion of an optical medium from outside to inside the framing; and a pin entrance on an outer surface of the framing, with the framing enclosing a main support unit to lift and/or lower to respectively couple and/or uncouple the inserted optical medium on/from a turn-table for recording and/or reproducing data from the optical medium, a slider to lift/lower the main unit, and a releasing unit to disengage portions of the slider from a driving source which drives the slider to manually move the slider upon insertion of a pin into the optical device, such that the pin entrance is aligned with the releasing unit for the disengaging of the portions of the slider from the driving source upon the insertion of the pin through the pin entrance.
